2.1.10 RSTP

The  Spanning-Tree  Protocol  (STP)  is  IEEE  802.1d  standardized  method  for  avoiding  loops  in
switched networks. Enable STP to ensure that only one path at a time is active between any two
nodes on the network.

The Rapid-Spanning-Tree-Protocol (RSTP) is a more advanced protocol than STP according to
IEEE  802.1w  standard.  RSTP  can  shorten  spanning  tree  convergent  time  while  network
topology is changed. A default diagram is shown below,
